Predator silhouette - self-adhesive foil - 11 predators on a sheet 30 x 40 cm

Rainbow Fantasy anti-collision stickers use modern holographic foil technology combined with hundreds of years of a proven methods of deterring birds with moving reflections of light to divert birds into glazed areas.

For hundreds of years, shiny pieces of moving wind material have been used successfully to protect agricultural products from birds, creating sharp moving reflections of light in all directions.

The holographic film creates these reflections with a small change in the angle of the observer. During the flight, the bird changes the angle of observation of a static object during flight practically every millisecond. The Rainbow Fantasy sticker thus creates continuous color reflections of rainbow colors in different colors, even for humans.

The moving reflections significantly influence the birds' decision to fly in the direction from which they come and thus significantly reduce the risk of birds hitting windows and glass surfaces, compared to other measures.

One of the most common causes of bird deaths is their collision with clear fillings, especially in greenhouses, atriums, shop windows and house windows, which pose a high risk to birds. Especially if there is some greenery or flowers behind or in front of them. Reflecting areas are also dangerous, in which the surroundings are displayed - trees, greenery, sky.

Unlike humans, birds have their eyes placed on the sides of their heads and therefore see sharply to the sides. During the flight, they pay attention to the space around them and under them, not the space in front of them. Birds move significantly faster than mammals in flight and cannot distinguish what reality is and what its mirror image is. They also do not know that the greenery is behind the glass and that the space in front of them is not free. The birds will head to the mirror area in the belief that they are flying to the safety of the green.

The reflections of the rainbow foil are transmitted in all directions (at an angle of 130 degrees) and are more visible for bird watching.

Stickers are the best known and longest-used tool for alerting birds to a glass obstacle. One "abandoned" sticker on a large window or greenhouse doesn't solve anything. For a long time, one silhouette of a predator that birds are afraid of was considered sufficient. It turned out to be dysfunctional, albeit still widely used, practice. For rainbow stickers, a distance of 30-40 cm between the stickers is usually sufficient.

Proven conclusion: Fantasy rainbow stickers against hitting birds into the windows increase visibility several times, thanks to the rainbow reflections when changing the angle of view, which creates the impression of movement. The birds are thus able to better detect the obstacle.
